STATEMENT ON ACADEMIC DISHONESTY
Academic dishonesty is unacceptable and will not be tolerated. Cheating, forgery, plagiarism and collusion in dishonest acts undermine the College’s educational mission and the student’s personal and intellectual growth. COSTATT students are expected to bear individual responsibility for their work and to uphold the ideal of academic Integrity. Any Student who attempts to compromise the academic process will be sanctioned.”– COSTAATT Academic, Integrity and Honesty Policies and Procedures Handbook.
A Quick Note on Citation
Plagiarism is the representation of someone else’s ideas or words as one’s own. It is a serious academic offence that includes:
- Presenting another person’s paper or ideas as original, submitting borrowed, purchased, ghost-written papers and documents downloaded from internet sites.
- Extensive paraphrasing- Flagrant failure to properly cite sources. This includes uncited ideas, quotations
and/ or words.Students are expected to implement the methods taught in COMM117, COMM118 and LIBS130and should be cognizant of the fact that credit will not be given for work found to be plagiarized. Repeated incidents of plagiarism will result in a failing grade and/or academic sanction.
COSTAATT requires students to adhere to the APA (American Psychology Association) citation standards that require in text citation and a reference list. Details of these requirements are as follows:
In text citation (Quotes/Paraphrasing)o Direct quotation
Use quotation marks and include page numbers (when quoting books, journals and periodicals) or paragraph number (para. when quoting online sources.
A quotation of 40 or more words should be formatted as a freestanding, indented block of text without quotation marks.
o Indirect quotation/paraphrasingo Citations from a secondary source
References list At the end of an assignment, the full bibliographic information for each source cited in
text should be provided. Do not use footnotes References must be listed in alphabetical order by author and should use the hanging
indent format.o Books / Reports / DVDs
Each reference should include four elements: Author/Editor/Producer Date Title Publication Information
Periodicals -Serials or periodicals are resources published on a regular basis, such as journals, magazines and newspapers. The elements to be included are:
Author(s) Date
13CHEM090: Introduction to Concepts in Chemistry I
